MARSH HAWK 246 



taking a few strokes, then gliding forward on spread wings, 

 or wheeling motionless. 



Its long tail and short, rounded wings, and the alter- 

 nation of iving-stroJce and periods of gliding, mark it as 

 either a Sharp-shinned Hawk, or a near relative, the Coop- 

 er's Hawk, and distinguish it from the other small hawk, the 

 Sparrow Hawk. When pursuing its prey, however, it does 

 not stop to glide, but flies with rapid wing-strokes, dashing 

 into a thicket where the frightened birds have taken refuge. 

 It is then to be distinguished from the Sparrow Hawk by 

 the entire absence of reddish-brown on the back. When it 

 perches, it chooses a limb more or less in shadow ; its tail 

 extends some distance beyond its folded wings, and is crossed 

 with several blackish bars. There is no way of surely tell- 

 ing a large female Sharp-shinned Hawk from a small male 

 Cooper's Hawk ; the male of the smaller species and the 

 female of the larger may, however, always be told by their 

 size. When the nest is approached, the parents utter a 

 cry suggesting " a Hairy Woodpecker's long call " (F. H. 

 Allen). (See Frontispiece.)
